DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.
[0013]
FIG. 1 is a vertical cross-sectional view showing a window frame mounting structure. In FIG. 1, 1 shows a window frame, and this window frame 1 is constituted by a vertical frame (not shown) arranged on the left and right sides, an upper frame 3 and a lower frame 5, and is formed on the inside thereof. A shoji 7 having a glass 6 is provided so as to be freely opened and closed. Reference numeral 8 denotes a handle. The upper frame 3 and the lower frame 5 have substantially the same structure, and each have two nail driving fins 9A and 9B integrally.
[0014]
The window frame 1 is fixed to the housing 12 by driving a nail 11 through the nail-fin 9. The housing 12 includes a pillar 12A, a load-bearing board 12B, and an interior board 12C, and an interior material 13 is installed on the indoor side.
[0015]
As shown in an enlarged view in FIG. 2, the upper frame 3 and the lower frame 5 are provided with main body frames 3A and 5A having two nail driving fins 9 and screws 15 at the ends of the main body frames 3A and 5A. The external frames 3B and 5B are detachably attached, and the external frames 3B and 5B are integrally provided with extending portions 3C and 5C that extend substantially flush with an outer surface 17A of an outer insulating material 17 described later. Is formed. Although not shown, the vertical frame has the same configuration. Since the main body frames 3A and 5A and the external frames 3B and 5B are divided, for example, when used in the filling method shown in FIG. 9 and when used in the outer insulation method shown in FIG. 3A and 5A can be shared.
[0016]
In this embodiment, the moisture-proof airtight sheet | seat 18, the airtight tape 19 grade | etc., Are affixed on the outer surface of the load-bearing board 12B which comprises the housing 12, and the said outer-layer heat insulating material 17 is affixed on it. The outer heat insulating material 17 is formed so that its outer shape is slightly larger, and the outer peripheral portion 17B is fitted and arranged so as to be pushed into the space A formed inside the extending portions 3C and 5C. desirable. This is because when there is no heat insulating material in the space A, air convection occurs in the space A, and the heat insulating performance between the outdoor side and the indoor side is impaired. However, this fitting arrangement significantly reduces the assembly workability of the outer heat insulating material 17. Therefore, in the embodiment shown in FIG. 1, the outer heat insulating material 17 is formed as small as the space A, and the space A formed therein is filled with, for example, foamed urethane 20. According to this, assembly workability does not fall.
[0017]
A moisture-proof and airtight sheet 21 is affixed to the outer surface of the outer heat insulating material 17. And the waterproof tape 23 straddles between the outer surface of the outer heat insulating material 17 and the said extension part 3C, 5C so that the clearance gap between this outer heat insulating material 17 and the upper frame 3 and the lower frame 5 may be covered. Pasted. Since the extending portions 3C and 5C extend substantially flush with the outer surface 17A of the outer heat insulating material 17, the work of applying the waterproof tape 23 is easy. The waterproof tape 23 may be provided only on the upper frame and the left and right vertical frames. In this case, it is desirable to provide a drainer on the lower frame side.
[0018]
FIG. 3 shows the corner 25 where the waterproof tape 23 overlaps. There is no need to fold the waterproof tape while bending it into a substantially L shape as in the past, and the workability when the waterproof tape 23 is affixed is improved, and a pinhole is formed at the corner 25 as in the prior art. It is never done and it can stabilize the rain.
[0019]
In addition, referring to FIG. 1, a concave portion 26 for receiving the screw 15 is formed in the connecting portion between the main body frame 3 </ b> A of the upper frame 3 and the external frame 3 </ b> B. The recess 26 formed in the upper frame 3 has a function of guiding rainwater that flows down along the outer surface 17A of the outer heat insulating material 17 to the outside. Reference numeral 27 denotes a backup material.
[0020]
FIG. 4 shows another embodiment.
[0021]
The upper frame 3 and the lower frame 5 include main body frames 3A and 5A having two nail-fitting fins 9A and 9B, and an external frame 103B fixed to the ends of the main body frames 3A and 5A via screws 15. 105B. The external frames 103B and 105B have a hollow portion 107, and the hollow portion 107 is fixed to the nailing fin 9A via a screw. Another nail driving fin 109A is integrally formed on the hollow portion 107, and the upper frame 3 and the lower frame 5 penetrate the nail driving fin 109A and the nail driving fin 9B to drive the nail 11 into the housing 12. It is fixed. A vertical frame (not shown) has the same configuration.
[0022]
In the present embodiment, as shown in FIG. 5, the hollow portion 107 is formed with an extending portion 111 that extends substantially flush with the outer surface 17 </ b> A of the outer heat insulating material 17. A surface 113 is formed in contact with the end of the tension insulation 17. According to this, since the extending part 111 extends substantially flush with the outer surface 17A of the outer heat insulating material 17, the work of applying the waterproof tape 23 becomes easy as in the above embodiment. Since the said surface 113 contacts the edge part of the outer-layer heat insulating material 17, compared with the thing of FIG. 1, the filling operation | work of fillings, such as foaming urethane 20, becomes unnecessary.
[0023]
FIGS. 6 and 7 show the joints between the main body frames 3A and 5A and the external frames 3B and 5B when the window frame has a two-part structure of the main body frames 3A and 5A and the external frames 3B and 5B. The seal structure is shown. In any case, the joint between the main body frames 3A and 5A and the external frames 3B and 5B is formed by the seal material 81 attached to the external frames 3B and 5B, the main body frames 3A and 5A, and the external frames 3B and 5B. Water is sealed with a sealing material 82 interposed on the joint surface. The sealing material 82 is driven from the direction of the arrow A into the gap between the joint surfaces after the main body frames 3A and 5A and the external frames 3B and 5B are connected by the screws 15.
[0024]
In FIG. 6, the receiving part 83 of the sealing material 82 is integrally formed with respect to the external frames 3B and 5B. The receiving portion 83 is a fin that extends substantially orthogonal to the joint surface, and extends over substantially the entire length of the external frames 3B and 5B. Moreover, in FIG. 7, the tapping screw hole part which comprises the receiving part 83 is integrally formed instead of the said fin. In any case, when the sealing material 82 is driven into the joint surface, the sealing material 82 is received by the receiving portion 83 formed of fins or tapping screw holes, so that the operation of driving the sealing material 82 into the joint surface is performed. It becomes easy. The sealing material 82 may be driven over the entire four sides of the window frame 1 having a four-sided frame, or may be configured to be driven only into the four corners of the four-sided frame. This is because water leakage is likely to occur at the corner.
[0025]
FIG. 8 shows yet another embodiment.
[0026]
In this embodiment, unlike the above embodiments, the upper frame 3 and the lower frame 5 are not divided into two parts and are integrally formed. The vertical frame has the same configuration, is not divided and formed integrally. According to this, for example, since the screwing operation with the screw 15 of FIG. 1 is not required, the assembling workability is improved, and the seal structure shown in FIGS. 6 and 7 is unnecessary. It is done.
[0027]
As mentioned above, although this invention was demonstrated based on one Embodiment, it is clear that this invention is not limited to this.
[0028]
For example, in the above-described embodiment, the waterproof tape is applied between the extension portion and the outer heat insulating material. However, when another member is attached to the outer surface of the outer heat insulating material, the outer surface of the different member is used. Needless to say, an extension portion is provided so as to be flush with each other, and a waterproof tape is attached between the extension portion and another member. In this case, the outer heat insulating material is configured including another member. In the embodiment of FIGS. 1 and 3, the upper frame 3, the lower frame 5, and the vertical frame (not shown) are composed of two parts, a main body frame and an external frame. Therefore, as described above, in the external thermal insulation method, the external frame is connected to the main body frame using the screws 15, but for example, in the case of the filling method shown in FIG. 5, it is sufficient to use only the main body frame. . In short, when the window frame is composed of two parts, a main body frame and an external frame, it is possible to combine the outer frame heat insulation method and the filling method.
[0029]
It goes without saying that the present invention can be applied to all sashes such as door sashes, sliding sashes, vertical sliding sashes, side sliding sashes, or open-type fixed sashes that do not have an open / close type shoji.
[0030]
【The invention's effect】
According to the first or third aspect of the present invention, at least the upper frame and the left and right vertical frames of the window frame are provided with extending portions that extend substantially flush with the outer surface of the outer heat insulating material, and extend substantially flush Since waterproof tape is pasted between the outer part and the outer insulation, there is no need to paste the waterproof tape while folding it into a generally L shape as before, and workability when pasting the waterproof tape In addition, pinholes do not occur at the corners where waterproof tapes overlap, and rain can be stabilized.
[0031]
